COMBINATION FAUCET.

Application filed. June 15, 1922. Serial No. 568,612.

To all LU/10771217717261, concern Be it known that 1, Jason T. JOHNSON,a citizen of United States, residing at Atlanta, in the county of Fultonand State of Georgia, have invented certain new and useful Improvementsin Combination Faucets, of which the. following is a specification,reference being had therein to the accompanying drawing.

The present invention relates generally to combination faucets forcontrolling the flow of a plurality of streams, such as hot and coldwater, and aims to provide a novel and improved valve structure of thatkind.

Another object is the provision of such a combination faucet or valveincluding novel means for controlling the flow of hot and cold water orother liquids, and also com-- prising a novel construction andassemblage of the component elements, to provide an efficient,convenient and practical faucet or valve which is also simple inconstruction and economical to manufacture, install and maintain.

A further object is the provision of such a faucet or valve including aslidable valve member instead of rotary valve members as disclosed in myPatent No. 1,336,286, granted April 6, 1920, and application Serial No.526,942, filed January 4, 1922.

With the foregoing and other objects in view, which will be apparent asthe description proceeds, the-invention resides in the construction andarrangement of parts, as hereinafter described and claimed, it beingunderstood that changes can be made within the scope of what is claimed,without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, whereinFigure 1 is a median vertical reaction of the faucet. portions beingshown in elevation.

' Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is an elevation of a modified construction, the discharge portionof the casing being shown in section.

Fig. 4 is a view similar to Fig. 1 showing another variation.

Fig. 5 is a cross section on the line 5-5 of Fig. 4.

The body or casing 10 is of suitable metal and has a vertical orlongitudinal chamber 11 preferably of rectangular or non-circular thecold and hot water inlets 12 and 13, re-

spectively, leading to the opposite sides of the smooth wall of saidchamber, between the ends thereof. The casing has bosses or connections14 for the hot and cold water supply pipes from which the inlets extendto the chamber, and said inlets are preferably wide transversely of thechamber and of minimum width longitudinally of the chamber, so as not torequire excessive longitudinal movement of the valve member. The lowerend of the casing terminates in a discharge nippel or nozzle 15, saidend of the casing having an outlet extending through said nozzle oroutlet portion, and the lower end portion of the chamber 11 is graduallyreduced in diameter or tapered, as at 16, so that the wall of thechamber converges and merges into the nozzle or outlet portion toprovide a valve seat at the upper end of said nozzle.

The valve member 17 is of a shape to fit snugly in the chamber 11 forlongitudinal sliding movement, but is constrained so as not to rotate.The stem or rod 18 for operating the valve member is swivelled through.said valve member, centrally within the chamber 11 and valve member,said stem extending loosely through a central opening in the valvemember, and having a flange or head 19 abutting the lower end of thevalve member. A valve tip or head 20 is secured to the flange 19 at the.lower end of the stem, and is of rubber, fibre or similar material, toseat snugly on the lower portion or seat of the casing over thedischarge outlet with a compression fit. This valve tip 20 closes thedischarge port of the valve when the valve member is forced down tight,thereby shutting off the flow from the casing. The stem 18 hasscrew-threads 21 above the valve member, and a nut 22 is threaded on thestem to bear against the upper end of the valve member 17, forcompelling the valve member to move with said stem, and to provide theswivel connection to permit the stem or rod to turn in the valve memberwith the valve member movable longitudinally with said stem. The valvemember has a recess or cavity 23 in the upper end thereof in which thenut 22 is disposed so that the nut and valve member can be nestedtogether when the valve member is raised, to provide a compactarrangement.

channels are adapted to register with the respective inletsorports -.l2and 13 in suecession, saidupperends of the passages be- ..inglocated atspaced :points longitudinally of the valve member, whereby the passageregisters with the inlet 12 beforethe pasfsage'25 registers with theinlet 13 when the valve member is slid upwardly. The lower .end ofthevalvemember l7 isot tapered or conical :form, with the valve tip 20at-the apex thereof, and the passages 24 and 25 openattheir lower endsat said conical end of the valve member atopposite sides of the valvetip20. I

In order toslide .the valve member when the stem '18 isrotated, a member26 is threaded into the-upper end of the casing and seats on a shoulder27 at .the upper end of the chamber 11, and said member 26 has a centraldropped nut portion 28 through which the threaded portion of the stem isscrewed, thereby compelling the stem to travel longitudinally when it isrotated for sliding the .valve member. The recess or cavity 23 willaccommodate the nut portion 28 when the valve member is moved to'itsuppermost position. v

The stem 18' has a portion 25) of reduced diameter projecting .out ofthe casing and havinga suitable handle 30, and a packing cap 31 isthreaded on the upper end portion of the casing. A disk 32 bears on theupper end of the casing and member 26 and ,packing 33 is confinedbetween said disk 32 and cap 31 for preventing leakage, the portion 29of the stem projectingthrough said disk, packing and cap. The droppedportion 28 is sufliciently spaced from the disk 32 to en able thethreaded portion 21 of the stem to travel upwardly the required amountto completely raise the valve member, without the threads entering thepacking. The memvher 26 is formed for .the engagement of a wrenchtherein to apply and remove said anember when the cap 31 and packinghave been removed from the casing.

When the valve stem 18 is screwed down tight, the valve member 17 isslid down so that it closes the inlets 12 and 13 and presses the tip 20over the outlet 15. Thus, both inlets and also the .outlet are closed,to pre vent the discharge of either hot or cold .water, or to preventthe backing up of either hot or cold water into the opposite supplypipe, inasmuch as eommnnieation between the inlets is shut ofi. Thiswill effectively prevent leakage when the valve is closed. By screwingthe 'stemupwardly, the

ly further, the passage 24 starts to move out of registration with theport 12, and the passage 25 starts to move into registration with the.hot water inlet 13, whereby hot and cold water are discharged -.throughthe valve member to mix within the lower portion 'of the chamber 11around the valve tip 20 and discharge through the outlet. 15. Thetemperature of the discharged water can be regulated by adjusting thevalve member upwardly and downwardly whereby the passagesQd and 25register more or less with'the corresponding inlets 12 and 13. It i willalso be observed that the streams ot' hot and cold water flowing throughin the passages or channels 25and 24,-respeetively, are

directed downwardly towardthe outlet, before the streams meetoneanother, and the tapered portion 16 ofthe casing will direct the streamstogether through the outlet. This will prevent the head-on collision ofthe streams as well as reducing the-objectionable noise or vibration ofthe fixture and plumbing. The streams are brought together gently butwill, nevertheless, mix thoroughly in passing to and through the outlet. The mixing of the hot and cold water is thus delayed until thestreams are 'di-' rected toward the outlet, which will minimize thedisturbance within the casing resulting from the discharging streams ofiwater under pressure and the commingling thereof. This will also reducethe agitation or spraying of the water when discharged from the outlet.By raising the valve member further, to bring the upper end o'f thepassage 24L completely above the inlet .12, with the passage .25 inregistration with the inlet 13, the fiow of cold water is shut ofl, andhot water alone is delivered, the flow of hot water being controlled orreduced by raising the valve member to gradually reduce the flow of hotWater by the partial movement of the passage 25 out of registration withthe hot water inlet 13.

then the flow of cold water being stopped,

just reverse to the manner, as above descrlbed, 1n ralsing the valvemember.

The pitch of the screw-threads can be suchas to require several turns ofthe stem tg-Slldfi the valve member to extreme post tions, or so as onlyto require a part of a complete turn of the stem by making thescrew-thread quicker.

Fig. 3 shows a similar faucet or valve, wherein the discharge portion isextended to one side to provide a horizontal nipple 15" for theconnection of a hose, pipe, or the like, which is especially desirablefor a shower device or appliance, shampoo device, or the like.

In the modified construct-ion shown in Figs. 4. and 5, the several partsare the same as described hereinbefore, excepting as hereinafter noted.The lower terminal of the valve stem 18 does not extend through thevalve member 17 but simple enters the upper end portion thereof, and isprovided with an annular groove 19 receiving a screw 19 or other elementen aged in the valve member for swivelling the stem to the valve member,instead of having the stem pass through the valve member and providedwith a flange 19 below the valve member, as seen in Fig. 1. In this casethe tip 20 is se cured direct to the lower end of the valve member, anddoes not rotate with the valve stem as with the first form, the tip 20having a short shank 20 entering a recess in the lower end of the valvemember, and the tip being secured to the valve member by means of ascrew 20* or the like. With the arrangement shown in Fig. 4:, the valvetip 20 is carried by the lower end of the valve member and does notturn, whereas, as seen in Fig. 1, the tip 20 is carried by the lower endof the valve stem to rotate. A further variation consists in the factthat the channels 24 and 25 are open throughout their lengths at thesides of the valve member. Otherwise, the construction as shown in Figs.4 and 5 is the same as shown in Figs. 1 and 2, and the operation issubstantially the same.

Having thus described the invention, what is claimed as new is 1. Avalve comprising a casing having inlets and an outlet, a valve memberslidable in the casing and having a conical end with a valve tip at theapex of said end to seat across said outlet, said valve member havingseparate channels extending to said conical end and adapted tocommunicate in succession with said inlets, and a stem connected to saidvalve member for sliding it in the casing.

2. A valve comprising a casing having side inlets and an outlet at oneend, a valve member slidable in said casing and having a conical endwith a valve tip at the apex of said end to seat across said outlet, anda stem connected to said valve member for sliding it in the casing, saidvalve member having separate channels at opposite sides of said stem andvalve tip extending to said conical end of the valve member, and adaptedto communicate in succession with said signature.
